Light & Motion Bluefin housings have a fitting that comes on there handles. This fitting can be unscrewed & better yet, contact your local dealer & order a pair from them.
I got mine from Pete Mooney at Scubapix.
The centre hole in the fitting is the same size as the hole in the Gates handles so it was just a matter of finding the right screws or nut & bolt combo & fitting them.
I used 316 stainless screws & a nyloc nut but you could easily cut a thread into the handle with a tap & dye & just use a screw.
Now my Sola 4000s are easily attached & unattached simply by pulling up the collar & twisting.
Hope that is of use for someone else.
Cheers Pete.
